Description
ebm-papst 6224NU is a high-performance DC axial fan featuring a 172 mm diameter by 51 mm depth circular profile, operating at a nominal 24 VDC with an 18 W power input. This unit utilizes a robust die-cast aluminum housing and a fiberglass-reinforced PA plastic impeller, supported by a dual ball bearing system for extended service life. The fan delivers a maximum airflow of 410 m³/h at a nominal speed of 3400 RPM while maintaining an IP 68 protection rating against dust and moisture ingress. Internal commutation electronics provide integrated protection against reverse polarity and rotor locking.
